LIQUID-DISPENSER.

Specification of Letters Patent.

Patented July 16, 1918.

Application filed April 28, 1917. Serial No. 165,131.

Letters Patent No. 1,139,129, issued to me' May' 11, 1915, and in Letters Patent No. 1,181,783, issued to me May 2, 1916.

The ob ect of the present invention is mainly to simplify and cheapen the apparatus, and render it more adapted to the exigencies of quick and frequent cleansing,

especially when used for the dispensing of milk, in which case sanitation is of vital importance. specific construction and arrangement of parts herein described and claimed,-a distinctive feature being the elimination of mixing chamber and valves and the connecting of the dispensing. faucet directly with the fioatable drain duct and with the main reservoir, thereby preventing possibility of back flow of the heavier liquid constituent into the fioatable drain duct when the faucet is closed. Hence the relative proportions tween the faucet and the floatable drain duct;

Fig. 4,, is an elevation of the inner end of the faucet plug shown in the preceding figures;

Fig. 5, is a view like unto Fig. 2, showing a modification;

Fig. 6, is a section taken upon plane of line 66, Fig. 5.

The dispensing receptacle or reservoir 1), is preferably although not necessarily of cylindrical s iape in horizontal cross section, and is inclosed ordinarily in an outer shell The invention consists in the or casing D, of sufficient size and capacity to contain a packing of ice, or a packing of non-conducting material, as may be found most expedient in adapting the apparatus to the character of the liquid constituents to be dispensed,it being understood that I herein by way of illustration describe the apparatus as adapted to the storage and dispensing of milk, without limiting myself to that specific purpose, to which however it is especially'adapted. The reservoir D, is provided with a removable cover cl, and is otherwise adapted to meet the requirements of practical use. I

In Figs. 1, 2, 3, and 4, the threaded inner end of the dispensing faucet-casing screws into a sleeve or bushing 0Z extending through the walls of the reservoir D, and

easing D, and through the intervening space; or connection is otherwise made with the interior of the reservoir D. In the modification shown in Figs. 5, and 6, the faucet C, is positioned mainly'in the space between the bottom of the reservoir'D, and the bottom of the casing D. In either arrange ment the casingc, of the faucet is formed with outlet ports i, 2'', which communicate Wlthw the interior of the reservoir'D,the one dutlet 2', opening directly thereinto,

while the other 2", communicates with the interior of the reservoir through the medium of the floatable drain duct: F. Both outlets 2', c", are adapted to communicate with the interior of the hollow plug 0,

when the latter is turned so that its port 01'. ports (as the case may be) coincide there-- with, and as shown in both Figs. 2 and 5, of the drawings, so as to afford a common means for the simultaneous discharge from the reservoir of both liquid constituents. In fact thehollow plug in this case, and in either arrangement shown, becomes the mixing ,and discharge chamber, and the only tirely feasable and satistactoiyin so far as The flea-table drain duct" l5, is pivotally supported upon a fulcrum-elbow 0, formed with a tubular coupling member a, one end formed with a cross sleeve or T fiwhich fits over said lateral extension 6 of the fulcrum elbow and is held thereon by a cap screw 6 engaging with the externally threaded end of the aforesaid lateral extension e of the fulcrum elbow e. Said lateral extension or trunnion e is formed with a port c, (Fig. 6) of shape and area suliicient to maintain.

continuous communication between the lower end of thefioat drain duct F, and the outlet passage through the elbow e, to the port 5, which delivers the lighter liquid constituent to the hollow plug 0, of the dispensing faucet C,

The free end of the coupling member e, of the fulcrum. elbow e, simi-ply fits snugly within the socket c of the aucet casing 0, so as to be readily detachable therefrom by simply pulling said coupling member 6, out of said socket 0',- thus freeing the fulcrum elbow c, and float drain duct F. Then, by the removal of the screw cap 6 the fulcrum extension 6 may be readily witln drawn from the cross T f, of the heat drain duct l8, so that all the parts and joints are rendered readily accessible and cleanable A float 7?, of any desired construction. or

configuration is attached to'the fioatabledrain-duct F, at or'near its upper extremity in suchrnanner as to maintain the mouth or inlet 7*, of the said duct F, slightly below the level of the liquid in the reservoir 'DQ Hence, obviously the upper strata of: liquid in the receptacle D, will always have access to said drain duct F, no matter what the height of the liquid level may be; nor

how much it may vary, vertically considered, as related to the outletsi, ii. I

The use of a mixing chamber and valve in connection with the outlets c',-', as set forth in the above mentioned patents is en- Which when closed effectually closes both casing having'a plurality of discharge pas navaose operativeness in concerned, but where milk is the liquid-dispensed and the apparatus has to; be frequently cleaned and scalded throughout, the vmixing chamber, valves, etc., render theproblem of perfect sanitationdiilicult and expensive. Furthermore the initial cost thereof is objectionable where a simple, cheap dispenser is a desideratum.

' I not only overcome these objections to my old form of dispensing apparatus by formins; the outlets i, i, directly in the faucet casing itself, but I also obviate all danger of the heavier liquid constituent rising in the floatable duct tube since the mixing; chamher is eliminated entirely, the constituents of the liquid dispensed meeting only in the hollow discharge plug of the faucet,

outlets 2', 1 the one from the other, so that there can be no communication between them, and no back flow into the fioatable drain duct. v

What I claim as my invention and desire to secure by Letters Patent is, v r 1, A mixing faucet for dispensing liquids of difierent specific gravities, comprising; a

sages and a faucet plughaving a central bore and an inlet and fitting in said casing capable of being turned to communicate with the passages in the casing, areservoir' in which said casing 15 removably secured so with its inner end substantially flush with thewall thereof, and a-fioatable drain duct having a tubular coupling me'mber'at its lower end removably fitting; within one of the discharge passages ofthe casing,

2., A mixing faucet for dispensing liquids of" difierent specific gravities, comprising'a casing having a plurality of discharge passages, and a faucet plug having a central bore and an inlet-therei-nto, said plug fit- 10o ting in said casing and capable of being turned to communicate with. the passages in said casing, a reservoir in the wall of which said casing. is removably inserted from the exterior with its inner end substantially 105 flush with the inner Wall of the reservoir, a fioatable drain duct and a fulcrum elbow supporting said duct and having a tubular couplingmember removably supported in one of the discharge passages of said casing. 11a- HARRY G LYONS.
